' Application and February 26, 1925. Serial No. 11,693.

'This invention aims to provide an improved separable fastener. In thedrawings, which ferred embodiments of my invention Figure 1 is a frontelevation of the fastener; v

Fig. 2 is a section on the line 22 of Fig.1; j Fig. 3 is a rearelevation of the socket; Fig. 4 is an elevational view of the socketcasing before attachment to a support; Fig. 5 is a side elevation of thesocketcasing shown in Fig. 4;

' Fig. 6 is a front elevation of the second '15- form of my invention,showing a different form of prong-receiving part from that shown in thefirst form;

Fig. 7 is a section on theline 7- -7 of Fig.

.6; and

Fig. 8 is a section on the line 8'-8 of Fig. {3,

illustrating the form that the carrying medium assumes when a stud hasbeen engaged with the socket and showing the freedom of the resilientwalls of the socket.

Referring to the drawings, 1 haveshown a simple, durable and inexpensivetype of snap fastener and two simple forms of prong-receiving clenchplates for securing the socket casing to'its support without cutting ahole in the support except for the attaching prongs.

The fastener illustrated in Figs. 1 through 5 includes a stud memberhaving a head 1, a neck 2 and a base portion 3 secured to a flexible suport 4 by a tubular rivet 5 upset within the lead 1 of the stud in theusual manner. The fastener also includes a socket having a casingsecured to a flexible support as more fully hereinafter described.

The socket casing, as illustrated, is pressed from a single piece ofmetal and presents a peripheral cylindrical wall 6, a second cylindricalwall 7' within the peripheral wall 6, and a third cylindrical wall 8within the 45, second wall. All of the walls are parallel with andspaced away from each other, as illustrated. The walls 6 and 7 areconnected by a web 9 at one end of the casing and the walls 7 and 8 areconnected by a web 10 at the opposite end of the casing, as illustratedin Fig. 2. At the free end of the third wall 8', I have provided areversely bent portion 11, which surrounds a stud-receiving aperture 12and forms means for engagement with the illustrate two nec k ofthe-stud. The walls 7 and 8 are made resilient to permit passage of thehead of the stud through the aperture 12 by dividing them 1nto resilientfingers'by a plurality of slots terminating in the web 9, as illustratedin Flgs. 2,3 and 4. These fingers are adapted to expand and contract topermit the head of the stud to pass through the stud-receiving apertureand the expansion and contraction of the fingers is distributed overtheir entire length and not concentrated at any one point. Thisconstruction, therefore,'is highly desirablebecause the socket is moreduraing set is greatly reduced. While the socket casing may be securedtoits flexible support 14 in any suitable manner, I prefer to secure itthereto by a clench plate or cap 15 and a plurality of prongs16. Theprongs 16 extend from the peripheral wall 6 of the casing through thesupport 14 where they are clenched. into' engagement with the cap 15 asillustrated.

Thus the casing is secured to the support 14 without weakening thefabric, as is the case when a central attaching rivet is passed througha hole in the fabric. The fabric 14 is also maintained in substantiallythe same plane throughout thereby avoiding unnecessary stretchingthereof. As illustrated in Figs. 2, 7 and 8, the fabric 14 is stretchedloosely over the resilient portions of the socket, and the cap member isspaced away from the fingers at least the thickness of the cloth, sothat there is no gripping of the. fabric above the fingers. Thus thefingers may contract and expand without interference from the support14. The cap memher is provided with a central dome 17 to provide a spaceinto which the fabric may be pressed when the stud and socket areengaged, as illustrated in Fig. 2.

Figs. 6, 7 and 8 illustrate the second form of cap member 18 incombination with a socket substantially asshown and described in thefirst preferred embodiment of my inble and the possibility ofthe fingersbecom- .sented by the socket casing, cure the socket casing to thesupport 14;

and upsetting the attaching pr A there;

1.. A fastener socket installation-including a cap part,a carryingmedium and a casing part, said casing part presenting aplu'rahtyofparallel concentrically arranged walls of substantially uniformheight,-some of said wallsbeing divided by a lurality of slits toprovide laterally yielda le stud-engaging means arranged about astud-receiving aperture, the cap part being located on one side of thecarrying medium and. the casing part on the other, and cooperatingattaching means in the form of prongs and prong-clenching means forsecuring said parts'together, the

' said walls and the said cap part presenting surfaces toward: thecarryin medium whichermit the carrying medium etween them to 'e insubstantially the same plane as the remainder of the carrlying medium.

2. A fastener soc et comprising, in combination, a oneiece socket casinglocated at one I side of a fiexi le fabric and presenting beyond theface of the fabric a continuous outer peripheral wall, a second wallwithin the peripheral wall and a third wall within the second wall, allof said walls being parallel and inthe same plane, a luralit of slitsextending through thesecon and thirdwallstoprovideresiliency,

and a plurality of rounded reversely bent portions resentedby said thirdwall to provide for su stantial engagement with the neck of a stud, saidreversely bent portions ,expansible with the second and third walls topermit smooth passage of the head of the stud into and out of engagementwith the socket, and

a means integral with the outer peripheral wall for cooperation withmeans located at the 0pposite face of the fabric thereby to secure thecasing to the flexible fabric.

3. A fastener socket including a casing lo cated at one side of aflexible support and having a peripheral wall presenting a plurality ofattaching prongs for cooperation with an attaching part located on theopposite'side of the flexible support for securing said casing to thesupport in such a manner that the support remains imperforate exceptwhere pierced by said prongs, a plurality of resilient stud-receivingfingers bent parallel with the peri heral wall, first in one directionand then in t e opposite direction and terminatin about a stud-receivinga erture, the parallel portions of each of said igers being spacedrelative to each other and relative to the soc the peripheral wallpermit free lateral flexing of said fingers over their entire lengthsthereby to permit the head of a stud'to ass between the free ends ofsaid fingers, an reduce to a minimum the gers becoming set;
